Key result
Specific inhibition of MMP-2 using siRNA significantly protected cardiomyocyte contractility from I/R-like injury and increased MLC1/2 expression compared to scramble siRNA.
Why the study?
Does specific inhibition of MMP-2 using siRNA protect cardiomyocyte contractility from ischemia-reperfusion injury in isolated rat cardiomyocytes?
Does specific inhibition of MMP-2 using siRNA protect cardiomyocyte contractility from ischemia-reperfusion injury in isolated rat cardiomyocytes?
Intracellular, cardiomyocyte-produced MMP-2 plays a significant role in sarcomeric protein turnover, and its inhibition protects against contractile dysfunction during ischemia-reperfusion injury.

MMP-2 siRNA may preserve contractility in isolated cardiomyocyte I/R injury; leaves open in vivo efficacy and clinical translation.
Lin et al. (2014) studied Ischemia reperfusion (I/R) injury. MMP-2 siRNA vs. scramble siRNA transfection was evaluated on Cardiomyocyte contractility and MLC1/2 expression. Specific inhibition of MMP-2 using siRNA significantly protected cardiomyocyte contractility from I/R-like injury and increased MLC1/2 expression compared to scramble siRNA.
